I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan looked at the saponified product and fell into deep thought. Although he is used to making by-products of everything, this is the first time that such a by-product has nothing to do with the original thing.

But anyway, this thing is more useful than candles.

Candles can only satisfy Liu Tan's momentary playfulness, but soap does not improve hygiene at 01:30.

Liu Tan had no choice but to put aside the issue of lanterns and make soap first.

By the way, I sent the produced product to Huo Guang and the others for a try.

Huo Guang was really amazed for a long time when he tried it for the first time. The cleaning ability of the soap is absolutely top-notch.

When they reach their level, they will pursue cleanliness and tidiness even more, but after all, the conditions are limited, and the things they use are not as powerful as soap.

Watching Huo Guang wash his hands repeatedly, Liu Tan couldn't help but stop him and said, "Okay, it's already very clean. I'll send you a few dollars later."

Huo Guang asked with some doubts: "Isn't Your Highness making lanterns these two days?"

He also came over to take a look, not to mention that those lanterns are indeed very beautiful, but as for Liu Tan’s mentioned that the Lantern Festival is attractive, he is actually not very good-looking. In essence, the population flow in Beijing is not very large, while those in other places Even if people travel, they generally don't choose the northern border country.

Not to mention that this piece of land is sparsely populated, it has always been the focus of competition between the big man and the Xiongnu. Just like Shuofang City was destroyed before, no one can guarantee that they can go back safely after arriving here, so why come here?Are you courting death?

In fact, it was very dangerous for Liu Che to choose to come here, and I don't know how the court agreed.

After hearing Huo Guang's question, Liu Tan's smile froze on his face, and finally he sighed and said, "Who says it's not, what I really want hasn't been made..."

Huo Guang: Well, you don’t need to say anything, I understand.

He can be said to be very used to talking about this kind of situation with Liu.

Liu Tan asked: "Don't talk about this, do you think this thing is easy to sell?"

Huo Guang thought for a while and said, "If you buy it, someone will buy it, it just depends on the price."

Liu Tan hesitated for a moment: "The price should not be too cheap in the short term."

Huo Guang said: "Then it's better to send it to Chang'an."

Liu Tan glanced at Huo Guang with some surprise. He really didn't expect that there are things that make money now, and Huo Guang's first thought was to send them to Chang'an.

It has to be said that Chang'an is the money bag, which may have been the consensus between him and Huo Guang.

After all, there are many people in Chang'an, and there are many rich people.

It's just that rich people are not fools. If you want to make money from others, your things must be good enough.

Liu Tan said: "Then I'll get some more first, because I still owe Princess Li Zhang a favor, and now her people are still in charge of the storage place, but the briquettes can't be sold, which is equivalent to making her lose money all the time." , this is not very good."

Huo Guang said: "Princess Li is not short of that money, not to mention His Highness also has difficulties, the princess will understand."

Liu Tan didn't quite agree: "I know it's their business, so I can't ignore it just because the eldest princess is sympathetic, right? I have to give something in return. I haven't thought about what else to do before, and now it's just right."

Huo Guang didn't discuss this with Liu Tan anymore, anyway, Liu Tan can do whatever he wants.

Liu Tan immediately asked people to start buying animal fat for making soap.

Of course, this kind of good thing must not forget the empress and prince, even Princess Yangxin and Princess Dangli.

However, the soap produced at the beginning actually didn't smell very good. After all, it was made of animal fat, so it would have a little smell.

It is not suitable for these people to give something with a smell, so Liu Tan can only find a way to add a little fragrance to the soap.

If you want to increase the fragrance, all you can choose now are natural floral fragrances. Liu Tan chose the simplest method: chop the petals and mix them with alcohol, and then filter out the residue.

What is left is actually a mixture of flower sap and alcohol.

This method is the simplest, and he also has the ingredients. The only disadvantage is that the fragrance is not so strong.

Liu Tan didn't care, he just wanted to cover up the smell of animal oil in the soap itself.

In addition to changing the taste, he also asked someone to make some special molds. Of course, the gifts must be beautiful.

So Liu Che, who was far away in Chang'an, received the strangest gift ever-several pieces of soap.

Oh, Liu Tan renamed it, called Soap.

At the beginning, Liu Che didn't care about the gifts Liu Tan gave him. Anyway, every time his son gave him something, it would be good.

Liu Ju read the letter relatively quickly. When he finished reading, he looked up and saw that his father was still reading the letter word by word. For a while, he couldn't help but feel a little strange. Most of the letters Liu Tan wrote this time were about the exchange market. things.

Before Jiang Chong came here, he had already said everything he had to say, and by the way, he turned Chang'an's attention back to Shuofang.

I have to say that Jiang Chong may not be very good at other aspects, but his acting is definitely top-notch.

Liu Tan just told him that once someone wants to attack the northern border country or Shuofang City, he will make him miserable, and then he doesn't know what Jiang Chong has imagined along the way, since he entered Chang'an, he automatically adjusted to the miserable one. files.

The scars on his face are not covered up anymore, oh, it’s not that they don’t cover up, it’s the kind of expression that shows inferiority because of the scars, but in fact it often attracts people’s eyes and attention to his face.

At first, Jiang Chong was ready to be attacked, but after being interviewed by Liu Che, Jiang Chong found that he was the one who cared about him all the time, and others were a little sympathetic.

It's true that the Han Dynasty court is controlled by Yan from top to bottom, but the problem is that Jiang Chong was originally good-looking, otherwise Liu Che would not have liked it, and now he is alone because the Xiongnu has become like this, it will only make people worse Anger and pity.

Even Liu Che expressed a few words of emotion, and Jiang Chong immediately started to let himself go after he figured it out. Anyway, Chang'an City has been full of difficulties in the northern border recently, and Shuofang City has not let go of such remarks until now.

It made both Liu Che and Liu Ju worry whether Liu Tan was suffering there again.

But...he looked down at the letter, Liu Tan never said in the letter what hardships he had suffered, but would tell them what delicious food and fun they had.

For example, the soap and the lanterns that are being made this time.

After Liu Chezai read it carefully, he put the letter on the desk and asked, "Where is the soap?"

He was anxious to read Liu Tan's letter just now and didn't pay attention to Xiangzao.

A round piece of soap was brought up, with beautiful flowers carved on it, just looking at it is pleasing to the eye.

Liu Ju moved closer to Liu Che and smelled a faint fragrance from a distance, he said strangely, "It's still fragrant!"

Liu Che randomly picked up a piece and smelled it, but he didn't dislike the smell, and then tried it according to what Liu Tanxin said, but he didn't feel anything. After washing, he did feel better than before, but it was just a little .

After trying it out, Liu Ju just said, "It's a lot more convenient."

At this time, the supreme father and son didn't take this thing too seriously. After all, no one in their class dared to let them not clean it.

Ordinary people in the Han Dynasty generally used plant ash, while the nobles generally used pig pancreas crushed and mixed with bean powder and spices, and the decontamination ability was also good.

Compared with what Liu Tan made before, they didn't think there was anything wrong.

It's just that this thing is really attractive to ordinary people below the middle class.

Liu Che and Liu Ju didn't feel at ease, while Chen Ajiao and the two eldest princesses just found it a novelty.

And after Liu Tan put it up in Chang'an's long-vacant store and sold it for a couple of yuan, it was sold out almost quickly.

After Liu Che found out, he pondered for a while and said, "Send an order to exempt the northern border country from taxes for one year."

Liu Ju raised his head in surprise: "Father?"

Liu Che rubbed his brows and said, "Before, I thought Tan'er was short of money, but now it seems that all the countries in the northern border are poor, so how can he be alone, I'm afraid that all the money will go to the treasury."

Therefore, it is not enough to just send money to Liu Tan, it is necessary to make the northern border countries not so poor.

Liu Ju was stunned for a moment, he really didn't think of this before.

Liu Ju's expression suddenly became very serious: "It's my son who ignored it. Presumably brother is also going to raise pigs to find a way out for the northern border country?"

Liu Che was stunned for a moment: "Raise pigs?"

Liu Yi said: "Yes, my brother said that soap is made of animal fat, among which pig fat is the most, so he wants to raise pigs."

It's because Liu Che didn't connect these two things for a while.

According to what his son said, the soap is to remove the stains on the body and hands, and the oil removal effect is also good, but the oil removal thing is made of oil?What kind of fairy magic is this?

But regardless of whether it was the magic of the fairy family or not, when Liu Che thought that his son had to work with lard in order to make money, his heart ached for a while.

If he hadn't been forced to do nothing, how could a good prince touch such a dirty thing?

At this time, both Liu Che and Liu Shi insisted that the soap was made by Liu Tan himself. This is also a long-standing cognition. After all, Liu Tan liked to do it himself no matter what he did before.

Until now, Liu Ju still remembers that when other princes and kings had the opportunity to enter Beijing, they frantically connected with each other, while his younger brother would just stay at home and toss in the mud when he entered Beijing.

Thinking of this, Liu Ju suddenly said: "In fact, even if my brother is rich, it may not be useful. The northern border country lacks clothing and food, even if you have money, you can't buy it. According to Yi Erchen, it is better to give my brother some food that is easy to preserve. .”

Liu Che sighed: "Go and prepare."

He couldn't think too much, if he thought too much, he wished to transfer Liu Tan back to Chang'an, even if he couldn't return to Chang'an, he wanted to change his fiefdom.

But intellectually, Liu Che felt that it was best to put Liu Tan there. Among other things, at least Liu Tan guarded Shuofang and the Hetao, and the Hetao area was too important to the big man.

Regardless of the geographical location, let’s just say that there is a pasture in the Hetao area with rich water and grass, which is most suitable for raising horses. If it falls into the hands of the Huns, it will really be like a tiger with wings added.

Before he was sure whether other people could hold the Hetao, Liu Che had to put him there even if his heart ached.

Liu Tan didn't know what a piece of soap made the supreme father and son think. Anyway, he only knew that Jiang Chong brought a bunch of food when he came back. The whole person was a little dazed.

But soon he put this matter behind him, because Jiang Chong also brought back a very happy news: the northern border country was exempted from taxes for one year.

Liu Tan turned to look at Huo Guang, and as expected, he saw a relaxed expression on his face.

Huo Guang let out a long breath and said, "That's great, the harvest has been poor this year, even if taxes are collected, I'm afraid it may not be able to collect much."

Liu Tan was taken aback when he heard this: "What? Bad harvest? How could there be a bad harvest?"

Huo Guang was helpless: "This year's rain is less than in previous years, so the harvest will be poor?"

Liu Tan stared: What's the matter?Guarding the Yellow River depends on God?
